Abstract

PURPOSE: To prepare α-dimethylamino-ε-caprolactam, economically, in an industrial scale, by reacting α-amino-ε-caprolactam with an N-methylol compound and formic acid at a specific temperature.
CONSTITUTION: α-Dimethylamino-ε-caprolactam is prepared by reacting α-amino- ε-caprolactam with an N-methylol compound and formic acid at 80W110°C. The N- methylol compound, which is formaldehyde source, is pref. α-dimethylamino-Nε- methylol-ε-caprolactam, however, other methylol compounds having amide group, ureide group, etc., and capable of forming methylol compound in the presence of formaldehyde and formic acid, can also be used. The compound may be mixed with formaldehyde before the reaction.
